BREAKING NEWS - BUILDING ABLAZE IN ATHENS AS RIOTS BREAK OUT
Rioting has spread across Athens with buildings set ablaze as more than 100,000 protesters gathered ahead of parliament's vote on a fresh raft of austerity measures.
TV footage showed a three-storey corner building completely engulfed in flames with riot officers looking on from the street, and firefighters trying to control the blaze.
The country's prime minister, Lucas Papademos, has warned of "uncontrolled chaos" if if the spending cuts are not approved.
Sky's Europe correspondent Robert Nisbet, in Athens, said thousands of police are in the area of the parliament building to deal with violence.
Thousands of protesters are in the area with more arriving all the time, including families with children, Nisbet added.
Tear gas has been fired into the crowd and police are armed with water canons.
